Watch my youtube videos for complete understanding on micrograph




Micrographs and Transactionability



Chapter1, Introduction

 

a. What are micrographs

. a kind of batch graph

. it is executed as a single process 

. they deployed to create micrograph object .mg file

. Normally they are used in service oriented architecture 

a) transaction processing

b) web services processing

. called by RUN MICROGRAPH component

b. Why we need micrographs

 

 

c. How to Setup Micrographs

d. Restrictions on Micrographs

   component folding

1. DB components 

2. file path name absolute

3. flows and layout - straight flow and serial layput

4. components must be foldable

5. graphs scripts - do not use these start and end scripts

6. no nesting 

7. phase break , single phase , no checkpoint

8. run mode - micrograph

9. partion_path , this_partion, no_of_partions()









Chapter2. About Micrograph Components

        

p. Run Micrograph

incount  1

outcount 2

package 

processing_timeout 0

memory_limit 200m

reject_threshold  abort on first reject

logging false

doc_transform

Mandatory Ports:

control port

status port

Optional Ports:

input and output ports

q. Micrograph Input

test_file:pathOfTestData

r. Micrograph Output

test_file:pathOfResultData







Chapter 3. Deploying a micrograph


m_deploy_micrograph <nameof.mpfile/.psetfile> <name of .mg file>

example

m_deploy_micrograph $PROJECT_DIR/mp/account_balance.mp $PROJECT_DIR/run/account_balance.mg


packgage:


ececution_spec::prepare_execution(control)=

begin

execution_spec.micrograph_object_file:1:if(control.soapheaders.soapaction=='balance') $PROJECT_DIR/run/account_balance.mg;

end;


status::create_status(execution_result,control)=

begin

status.success::1;

status.*::control.*;


end;



Chapter 3  Example Micrograph

Abinitio Interview Question # 1 - Write Multiple Files in Abinitio

Image
 Question :  I get records of various region in huge volume ,  we want to write the records in region specific files.   How to achieve that? View the explanation in the below video: Answer: -WMF WMF: filename::get_filename(in)= begin let string("") l_filename=string_substring(in.data.region); filename::string_concat($AI_SERIAL,"/",l_filename.dat); end; out::reformat(in)= begin out::in.data; end; OUTPUT DML-: DML record string(int) filename; string(integer(4)) file_contents; end; RMF: filename::get_filename(in)= begin filename::string_concat($AI_SERIAL,"/",in.filename); end; out::reformat(read,filename,in)= begin out.file_contents::read; out.filename::filename; end; Please view my youtube channel  DataPundit

  Metaprogramming in Abinitio 1. How to create output DML dynamically based in INPUT DML 2. How to create intermediate transform( XFR) dynamically based on INPUT DML      Please See my you tube video for explanation : PART 1 PART 2 For Example, let us say, we have an Input DML as below-: cat input.dml record string(",") name; decimal(",") age; decimal(",") salary; string(",") aadharid; date("yyyy-mm-dd")(",") joiningdate; string(",") mobileno=NULL; string(",") dlno=NULL; string(",") passportnumber=NULL; end; (1.1) prepare a new DML based on input DML i.e. add fields, remove fields, modify type Graph based parameters: ===================================================================== input_dml=$DIR/input.dml  [interpretation = constant] input_dml_info =$[read_type(input_dml)]   [interpretation = pdl] /* Define functions in AB_DML_DEFS */ AB_DML_DEFS= $[ out:: dynamic_dml_gen(input_dml_info)= beg...

Next In Sequence in ABinitio | How next_in_sequence() works in MFS

Image
https://youtu.be/JdDDpjZcv-4 next_in_sequence() working in Abinitio: Definition -      within a single process(component) , this gives successive number.   next_in_sequence()>1 i.e. all records whose occurance is 2 and more in the file.      for example dataset below:    employeeName ram shyam ravi hanuman shekhar seeta geeta shayama vidushi vishakha If we process by condition next_in_sequence()>1 then the output will be [first record will be removed] shyam ravi hanuman shekhar seeta geeta shayama vidushi vishakha 2. next_in_sequence() with reformat  - rely -  FieldA 1a 2a 3a 4a 5a 6a 7a Example 1 (serial processing)--> Reformat   count=2      select:   next_in_sequence()<900      Transofom1:   out:reformat(in)=   begin   out.*::in.*;   out.Seq-No::next_in_sequence();   end;      Transform2:   out:reformat(in)=   begin   out.*:...
